BitTorrent, the popular file sharing program, has been spruced up with a new user interface and queuing features. Version 4.0 of Bram Cohen's official BitTorrent client, the first major upgrade since 3.4.2 in Spring 2004, also remembers what users were doing before a restart. The feature allows users to more easily pick up where they left off. [

# 2005-03-07: 4.0.0 is now available.
Changes since the last stable release:

* All new queue-based user interface
* Many options are now modifiable from the interface, including upload rate
* Lots of other interface improvements
* Extra stats are visible, for those who like it
* Remembers what it was doing across restarts
* New .torrent maker "btmaketorrentgui" replaces "btcompletedir"
* Better performance, as always
* License has changed to the BitTorrent Open Source License
* Torrent fields are correctly created and interpreted as utf8
* Too many little things to list

A few technical notes, for those interested:

* Single port: launchmany can seed and client can download many files from a single port and thread
* Interface now uses GTK instead of wxWidgets
* BitTorrent packets are marked as bulk data to make traffic shaping easier
